I had not been following along as much as I would like; I still need to go back and catch up, but I did read this post. I got so excited that someone else was still working on their half marathon trip report.
Then I realized you did the Wine & Dine. I did the Princess.

I must find that shirt......
That expo looks familiar! It was set up and crowded just like the Princess one! The shirts I bought at the expo at both the Princess and
Disneyland halves are like that..."I did it!" on the front and the map on the back. I also was hoping I didn't jinx myself by buying it ahead of time! (I kept the receipt until after the race!

)
The whole "13.1 miles....what was I thinking?!?" has crossed my mind many times too! I can't wait to read about your race experience, especially with it being at night!
